Abstract

fetched live from OpenAlex

Automated road tracking is important for map revision but is currently not reliable enough to be useful for industrial applications. Consequently semi-automatic road tracking has become the preferred solution. In this paper we introduce a road tracking system based on particle filtering and human-computer interactions. Particle filters were used to estimate road axis points. During the estimation and human-computer interaction, new reference profiles were generated and stored in the road template memory for future correlation analysis, thus covering the space of road profiles. Human input provided the road tracker with initial estimates, updated state parameters and multiple reference profiles. This approach has resulted in remarkable improvements in efficiency, compared to the human-only approach while preserving robustness and accuracy. 1

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
